I would not object to some effects clean up and fixes (e.g. garbage mattes, lightsabres, etc.)
Also, I would be OK with certain non-distracting changes such as the detention block corridor and the tractor beam font.
(Using the DVD version of 'Raiders' as an example, only a tiny minority of people complained about the digital removal of the snake reflection, boulder track, blue-screen fringes and so on.)
